STOVE-PIPE THIMBLE.

SPECIFICATION forming part of Letters Patent No. 315,988, dated April 14, 1885. Application and July 31,1884. (No model.)

To ctZZ whom it may concern.-

Be it known that I, GEORGE WV. VVOOD- BORNE, a citizen of the United States, residing at Uhrichsville, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Stove-Pipe Thimbles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to stove-pipe thimblcs, and has for its object the providing of a simple structure which will be fitted to receive the stove-pipe or the cap-piece; and it consists in the construction of the thimble with sheet-iron body and cast rim adapted thereto, and provided with circumferential slots for the lugs of the cap-piece.

It also consists in the cappicce formed of a cast ring, a sheet iron or tin cover fitted to said ring, and secured thereto in the manner presently more fully described.

It consists, further, in other improvements, all of which will be explained. a

In the drawings, Figure 1 is aside, and Fig. 2 a front, View of my improvement. Fig. 3is a section on line m 05, Fig. 2. Fig. 4 is a rear view of the cap. Fig. 5 is a side view of the cap-cover. Fig. 6 is a perspective view of the thimble and a stovepipe, and showing the stove-pipe applied to the thimble in dotted lines. Fig. 7 is a detached section of the cap-ring on line y 3 Fig. 4., and Fig. 8 shows one form of utilizing my invention.

The thimble proper is composed of the sheetiron body A, bent into cylindrical form, and having its inner end slashed and turned radially outward, forming a flange which fits against the inner side of a chimney wall around the stove-pipe hole and retains the thimble in place. Where the thimbleis being fitted to a chimney already built, it may have its inner end inserted through the hole before bending out the slashed flange, and when properly adjusted a hand may be passed through the thimble, and with ahammer properly bend out the flange so as to retain the thimble in place.

The thimble-rimBis formed with the cylindrical flange B and the radial flange B The former for about half itslength is slipped over the outer end of the body A, and is riveted thereto at O, as shown.

In practice I prefer to form flange B on its inner side with a continuous groove or rabbet, b, in which is seated the end of the body A. It will be noticed the rabbet is made of a depth equal to the thickness of the metal of body A, so that the perimeter of parts B and A are flush with each other. This is most clearly shown in Fig. 3. This makes a neat fit, and is particularly desired, because thereby the insertion of the stove-pipe is rendered easier, as will be understood.

The flange B is out out at b" to form theslot D, the forward wall, at, of which is the flange B and the rear wall of which is the forward edge of the body A, as shown in Figs. 1 and 6. At its rear end the slot D gradually tapers, so that the tongue on the cap, presently described,will bind thereagainst in the operation of the device. By thus cutting out the flange or wing B the slot D may be conveniently formed by casting, the weight of the rim is reduced, and the strength of same is not materially impaired. The tongues on the cap-piece are inserted into groove D through a small notch, D, out from the inner side of the wing B and leading into the forward end of the slot, as will be understood from Fig. 6.

The flange B has formed in itsinnerside, at its outer end, a groove, B, fitted to receive the ring of the cap, as shown in Figs. 3 and 6.

- The cap is composed of the ring E and the cover F. Ring E is formed with circumferential wing E and radial wing E The wing E is provided with the tongues G G, and has formed in it a notch, e, for the one end of the coverrod, and diametrically opposite said hole 6 it has a notch, e, for the other or hook end of such rod.

The wing E is rabbeted to receive the edge of ;the cover F. This cover F has a handle, F, on its outer side, and a central tube or bearing, F on its inner side for the retainingrod, which is journaled in said bearing. The

ends f andf of this rod are bent from the bearing-point and out of line therewith, and being made of spring metal have a tension to ward the cover when the rod is turned to the position shown in Fig. 3. I11 applying the cover the rod is first turned to the position shown in Fig. 5, and is applied to the ring by slipping the endf into the notch ein the wing E until the end fcan be slipped through the ring E and engaged with notch e, when the cover is adjusted into position in the ring. The retaining-rod is now in the position shown in Fig. 5. If it be turned to that shown in- Fig. 3, the tension of its arms ff will be against the wing E and the cover be firmly secured in position. The handle of this cover when it and the ring are united may be employed for manipulating the cap into or out of connection with the thimble.

In applying the cap to the thimble the tongues of the cap are slipped through the notches D in flange 13 into groove D, when the cap is turned into the groove and tightened in the tapered end thereof, as will be understood from Fig. 1.

By using a pin or tongue, H, properly arranged on a stove-pipe, H, the stove-pipe may be adjusted into connection with and secured to the thimble, the pin H being engaged with slot D D, as indicated in dotted lines, Fig. 6.

By forming my cap with the ring and the removable cover it will be seen that by removing' the cap astove-pipe fitting the bore of the thimble may be inserted. Then by detaching the cover from the cap-ring and applying the ring to the thimble the device is adapted to receive a stove-pipe fitted to the inner bore of the cap-ring, as will be understood. These results, it will be seen, I attain by making the cap of the ring and cover de-" tachable, as described.

In Fig. Sis shown an arrangement of parts illustrative of the one manner of using my device and for which the invention is designed. It consists, as will be seen, in providing the circumferential wing of the cap-ring with an opening or openings, e through which a pin or nail may be driven and forced through a stove-pipe, as will be seen. By this means the ring may be easily secured to the stovepipe and in its turn conveniently connect the stove-pipe to the thimble.

By this form of connection, it will be seen, I save the considerablelength of stove-pipe usually inserted into a thimble, and also avoid the danger ofthe pipe being slipped so far into the thimble as to be closed by the chimneywall and thus become defective in draft.

Having thus described my invention, what I claim, and desire'to secure by Letters Patent, 1s

1. The stove-pipe thimble composed of the sheet-iron body A and the cast rim B, formed with flanges B B the flange B being formed with a rabbet b, fitted to receive the body A, and being cut out at 6 whereby the slot D is formed between the flange Band the end of body A, the flange B being formed with a rabbet, 13", and a notch, D, combined with a cap-ring having'tongues G, substantially as and for the purposes set forth.

2. The combination of the stove-pipe thimble and the cap consisting of ring E, having notches e e, the cover F, provided with bearing F", and the rod journaled in said bearings and having its ends f f adapted to engage the notches e e, substantially as set forth.

In testimony whereof I affix my signature in presence'of two witnesses. V
